This is a decent start.. some things may have changed but a general method:
Pottery - Unfired Spherical Bottle - Can be maxed and trophy maxed just using air-infused spring water from Olwen (CoV WW) (In Question)
Brewing can be brought to 248 with Minotaur Hero's Brew and then maxed with Kaladim Constitutional, grab ground spawns. or Brut Champagne (hope you're rich)
Fletching - CLASS 9 Steel Fearbone Arrow (Small Nock) - Can Max arrow with 2 components from the naeyas in Shard's Landing at port in.
Fishing - Fish
Baking, - Broiled Raxil Fish - Fish in Argath will max trophy and get you 300.
Tailoring - use glove patterns silk and pelts.
Smithing - use tungsten ore ultimately.. to max
Make Poison - Mind Melt (Mt Death Mineral Salt) (Droga,Nurga).. that is all
Tinkering - I think it is is far easier and cheaper to do all the other tradeskills, do the 3.0 pre-quest and then just make black powder bombs and stuff to max tinkering.
Jewelcraft - Unless you have an abundance of the cut gems, foraging or getting geodes is a good way to make it simplified but you will be chucking cash down the drain, but hey, you will be 300!
Alchemy - Distillate of Alacrity IX - recipe that will get you to 300 (Deepwater Ink) (Plane of Water)
Research - easiest I know is the focused spell casting with binding powders, also if you get the other 7 and the 3.0 coldain prequest you can do the Tradeskill Alliance combines to get to 300+
